The problem is that Octane reads only gamma value from icc not color - just like Windows by default. Only fully color managament aplications like PS can read and implement color tables too. Cinema Picture Viewer can do that too.

I have also been troubled on this problem for a long time until I used the ACES/OCIO and modified something in it's config.ocio.
Now, the live viewer is the same colors as pv that has been calibrated by the icc profile.

The majority of steps is referred to this guy's video tutorial although the content is for Blender.

I'm not an expert on color management, but I guess it's a common problem with wide color gamut monitors. You may be possible to check whether there are no gamut profile in the oversaturated pictures, such as sRGB IEC61966-2.1, Adobe RGB (1998). The menu bar > Assign Profile in PS should also be given the same settings.
In C4D, the Rendering settings > Save > Image Color Profile also need the same settings to display correctly in pv.

After my test just now. Besides the above-mentioned settings, it's still necessary to instal a monitor calibration profile to display the correct color. As SSmolak said above,"The problem is that Octane reads only gamma value from icc not color - just like Windows by default. Only fully color managament aplications like PS can read and implement color tables too. Cinema Picture Viewer can do that too."

I guess the best way to display correctly without using any calibration profile is to change the monitor settings to sRGB mode.

You are right. After diving into that page, I think the image appears oversaturated in that case is normal in sRGB gamut environment. It have nothing to do with calibration or monitor. The main purpose of color calibration for me is wanted monitor to display colors more correctly. However, it has led to LV and PV are non-identical that need to be solved through informal methods. But overall the final effect is satisfactory.
